Application

(R)-PPhos is a versatile white solid ligand that plays a crucial role in asymmetric hydrogenation processes. Its primary purpose is to facilitate the hydrogenation of substrates such as β-keto esters, 2-arylacrylates, aryl ketones, and α-dehydroamino acids, making it an essential component in this new class of highly effective chiral dipyridylphosphine ligands. In addition to these applications, (R)-PPhos is also used in the palladium-catalyzed asymmetric bis-alkoxycarbonylation of styrene, further demonstrating its wide-ranging utility in chemical synthesis.
